Description

Technical Field

[0001] This utility model relates to the field of oil leakage prevention atomizing core technology, specifically an oil leakage prevention atomizing core based on a movable core structure. Background Technology

[0002] Atomizing coils, also known as atomizers, break down liquids into fine mist particles through heating or other methods, making them easier to inhale or absorb.

[0003] When existing atomizer cores are left unused for a period of time, the absorbent cotton will continuously absorb e-liquid. When the absorbent cotton becomes saturated, it will leak or drip e-liquid. In this case, the e-liquid will seep through the air intake hole on the lower electrode of the atomizer core to the lower base, and then permeate out through the contact surfaces of various components.

[0004] To address the aforementioned deficiencies, Chinese Patent Publication No. CN206213277U discloses a leak-proof e-cigarette core and e-cigarette, comprising an electrode assembly, a heating assembly, an atomizing tube, and a shell. The electrode assembly is installed at the end of the atomizing tube; the heating assembly is located inside the cavity of the atomizing tube; the outer wall of the atomizing tube is recessed inward to form a concave plane and a tangential plane, with an oil guide hole on the concave plane communicating with the cavity of the atomizing tube, and an air inlet on the tangential plane communicating with the cavity of the atomizing tube; the shell is fitted over the atomizing tube, with its inner wall abutting against the outer wall of the atomizing tube, so that an oil filling cavity is formed between the shell and the concave plane, and an air inlet channel communicating with the external airflow is formed between the shell and the tangential plane, with the oil filling cavity and the air inlet channel being separated from each other. The shell has an oil hole communicating with the oil filling cavity. Since the air inlet is no longer located on the electrode assembly, there will be no leakage of e-liquid through the electrode assembly.

[0005] The device described above uses the oil filling chamber and air intake channel to separate each other during use, ensuring that the e-liquid will not leak from the electrode assembly. However, after smoking, the condensed e-liquid in the device will collect in the oil-proof structure for storage. The accumulated e-liquid will flow out from the atomizer, causing a short circuit. Utility Model Content

[0006] The purpose of this invention is to provide a leak-proof atomizing core based on a movable core structure to solve the problem of short circuits caused by accumulated e-liquid leakage in the aforementioned background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof atomizing core based on a movable core structure, comprising a cotton-wrapped swab, an oil-guiding cotton on the outer surface of the cotton-wrapped swab, a metal bracket on the outer surface of the oil-guiding cotton, an oil-guiding cotton tube on the outer surface of the metal bracket, a metal cover on the outer surface of the oil-guiding cotton tube, a movable core movably sleeved on the outer surface of the metal cover, an oil inlet hole on the inner side of the metal cover, a connecting cap at the interface of the metal cover, an upper sealing silicone on the end of the movable core near the connecting cap, a movable core fixing ring on the outer surface of the upper sealing silicone, a spool on the end of the movable core away from the connecting cap, a lower sealing silicone on the inner side of the movable core, and a driving mechanism at the connecting end of the movable core, the driving mechanism being used to drive the movable core to seal the oil inlet hole.

[0008] Furthermore, the driving mechanism includes a spring, which is fixedly installed at the connecting end of the movable core. A fixed core is provided on the inner side of the spool, and the spring is disposed between the movable core and the fixed core.

[0009] Furthermore, an air inlet is provided on the inner side of the hardware bracket, and a clip is sleeved on the end of the hardware bracket away from the connecting cover.

[0010] Furthermore, the outer surface of the card is provided with a bracket fixing ring, and the outer surface of the bracket fixing ring is provided with a fixing core.

[0011] Furthermore, copper wire is wound around the outer surface of the spool.

[0012] Furthermore, a heating mesh is provided on the inner side of the oil-guiding cotton, and a clip is provided on the outer surface of the heating mesh away from the oil-guiding cotton.

[0013] Furthermore, the inner side of the movable core fixing ring is provided with a metal cover.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The drive mechanism facilitates the sealing of the oil inlet hole of the metal cover by driving the movable core, avoiding the continuous absorption of e-liquid by the oil guide cotton, which leads to dripping or seepage of oil. The oil inlet hole of the metal cover and the air inlet hole of the metal bracket adopt a separate sealing design to ensure that the outside atmosphere can enter the tube through the air inlet hole, while the e-liquid enters the tube through the oil inlet hole, ensuring that the equipment can stably obtain e-liquid and air.

[0016] (2) When the copper wire is energized, the fixed core is magnetized by the current of the energized copper wire and generates magnetism. At this time, the movable core is moved by magnetic attraction. After the movable core moves, the movable core leaks the oil inlet hole opened in the hardware cover. At this time, the e-liquid is absorbed by the oil guide cotton through the oil inlet hole. The heating mesh heats and atomizes the e-liquid on the oil guide cotton, so that it is inhaled by the user. When the copper wire is de-energized, the movable core is pushed back to its original position by the compressed telescopic spring. The top of the movable core blocks the oil inlet hole by cooperating with the upper sealing silicone, so as to avoid the oil guide cotton from continuously absorbing e-liquid and causing oil leakage.

[0017] (3) To prevent e-liquid from separating and leaking, the air inlet of the hardware bracket and the oil inlet of the hardware cover are separated from each other and are sealed to prevent e-liquid from leaking from the air inlet when not in use.

[0018] (4) Use bracket fixing rings and clips to fix the heating net, use the heating net to heat the oil-guiding cotton, and use the movable core fixing ring to prevent loosening or falling off under vibration and shock conditions, so as to ensure the stability and safety of the movable core during use.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: Please refer to Figures 1-2 This utility model provides the following technical solution: a leak-proof atomizing core based on a movable core structure, including a cotton swab 1, an oil-guiding cotton 10 on the outer surface of the cotton swab 1, a hardware bracket 5 on the outer surface of the oil-guiding cotton 10, an oil-guiding cotton tube 4 on the outer surface of the hardware bracket 5, a hardware cover 3 on the outer surface of the oil-guiding cotton tube 4, a movable core 8 movably sleeved on the outer surface of the hardware cover 3, an oil inlet hole on the inner side of the hardware cover 3, a connecting cover 2 at the interface of the hardware cover 3, an upper sealing silicone 7 at one end of the movable core 8 near the connecting cover 2, a movable core fixing ring 6 on the outer surface of the upper sealing silicone 7, a spool 16 at one end of the movable core 8 away from the connecting cover 2, a lower sealing silicone 9 on the inner side of the movable core 8, and a driving mechanism at the connecting end of the movable core 8, the driving mechanism being used to drive the movable core 8 to seal the oil inlet hole.

[0028] The drive mechanism facilitates the sealing of the oil inlet hole of the metal cover 3 by driving the movable core 8, thus preventing the oil guide cotton 10 from continuously absorbing e-liquid and causing dripping or seepage. Furthermore, the oil inlet hole of the metal cover 3 and the air inlet hole of the metal bracket 5 adopt a separate sealing design to ensure that the outside atmosphere can enter the cavity through the air inlet hole, while the e-liquid enters the cavity through the oil inlet hole, ensuring that the device can stably obtain e-liquid and air.

[0029] Example 2: Based on Example 1, please refer to... Figures 2-5 The fixed core 15 is also disclosed, and its specific structure is as follows: the drive mechanism includes a spring 14, which is fixedly installed at the connecting end of the movable core 8. The fixed core 15 is provided on the inner side of the spool 16, and the spring 14 is located between the movable core 8 and the fixed core 15. An air inlet is provided on the inner side of the hardware bracket 5. A clip 12 is sleeved on the end of the hardware bracket 5 away from the connecting cover 2. A bracket fixing ring 13 is provided on the outer surface of the clip 12, and the fixed core 15 is provided on the outer surface of the bracket fixing ring 13.

[0030] When copper wire 17 is energized, Figure 2It is known that the fixed core 15 becomes magnetic after being magnetized by the current of the energized copper wire 17. At this time, the movable core 8, made of metal, moves by magnetic attraction. After the movable core 8 moves, it leaks the oil inlet hole opened in the metal cover 3. At this time, the e-liquid is absorbed by the oil guide cotton 10 through the oil inlet hole. The heating mesh 11 heats and atomizes the e-liquid on the oil guide cotton 10, which is then inhaled by the user. When the copper wire 17 is de-energized, the movable core 8 is pushed back to its original position by the compressed telescopic spring 14. The top of the movable core 8, through its cooperation with the upper sealing silicone 7, blocks the oil inlet hole, thereby preventing the oil guide cotton 10 from continuously absorbing e-liquid and causing leakage. Figure 5 It can be seen that the air inlet of the hardware bracket 5 and the oil inlet of the hardware cover 3 are separated from each other and are sealed to ensure stable flow of e-liquid.

[0031] Example 3: Based on Example 1, please refer to... Figures 5-6 The heating mesh 11 was also disclosed, and its specific structure is as follows: copper wire 17 is wound on the outer surface of the spool 16, the heating mesh 11 is provided on the inner side of the oil-guiding cotton 10, the outer surface of the heating mesh 11 away from the oil-guiding cotton 10 is provided with a clip 12, and the inner side of the movable core fixing ring 6 is provided with a hardware cover 3.

[0032] The heating mesh 11 is fixed using the bracket fixing ring 13 and the clip 12. Figure 6 It can be seen that the heating net 11 is used to heat the oil-guiding cotton 10, and the movable core fixing ring 6 is used to prevent it from loosening or falling off under vibration, thus ensuring the stability and safety of the movable core 8 during use.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
